The City of Vernon, with a population of 32,000, is located in the semi-arid
Okanagan Valley of south central British Columbia, Canada. Following secondary
treatment by trickling filters, Vernon's treated wastewater is pumped into an 8,000
acre foot reservoir and is stored up to a year before being chlorinated and
irrigated on 1,000 Ha (2,500 acres) of nearby water-thirsty land. Annually,
during a 6-month irrigation season, over 4.5 million cubic meters (1.2 billion US
gallons) of nutrient rich reclaimed water is beneficially re-used. The program is
in keeping with a City policy of not discharging treated wastewater at any level
of treatment into a watercourse, except on an emergency basis. However, demands
on freshwater and the production of wastewater are increasing due to population
growth. A review of Vernon's 1985 Liquid Waste Management Plan (LWMP) was
initiated to examine wastewater management technology and to plan for the next 20
to 40 years. One of the conclusions of the review was that the integration of
water and wastewater planning involving dual distribution reuse systems is the
least costly and most environmentally responsible approach for the City to
pursue. This paper summarizes Vernon's proposed dual water distribution system in
which reclaimed water will be used for urban irrigation in addition to its
current uses. Includes table.
